Squirrels in the loft

For some years my cousin has been having problems with the squirrels in his loft. He has a massive garden with lots of shrubs and trees. There is constant noise in his loft, and also squirrel droppings. The problem persists even after he has had all the visible gaps blocked using some chickenwire. The pest control come for a few weeks and then sign off saying that since the poison that they leave has not been eaten by the squirrels there isn't much else that they can do. Please can you help. You may have had similar experiences. How did you get rid of the squirrels. By the way his family and children are afraid to go in the loft because of the squirrels.

Are they Grey or Red Squirrels ?
If they are grey they can be shot - they are classed as vermin as they are a non-native species - Reds however are native and are protected - I'm sure the RSPCA could advise you on the best course of action.

Thank you for your replies. They are grey squirrels. Can't understand why the Pest Control from the Council don't use a baited cage to catch them. I understand that the insurance companies do not cover any damages caused by the squirrels. Is that true?

I can vouch for their destructiveness - had them plus bats, an owl & a flock of starlings in my previous old house. Had the conservation people round & had to wait til the bats became active (April) then gave the roof space a good clean & repaired & treated all the holes they had made under the eaves.
That got rid of the whole menagerie without killing anything!
